The Hinged 19mm Rod Mount with 15mm Insert is used to mount your M21VE or M26VE lens motor onto a rod system. The rod mount features a 19mm rod port and it includes a 15mm bushing if you prefer to mount your motor onto a 15mm LWS rod. The mount is hinged, making it easier to open for mounting, and it closes around the rod. It is secured onto the rod with a locking lever.
